feat(posts): full-width body for image-less posts (drop dead 'no images' box)

Text-only Patreon posts (WIP/announcement/poll — the bulk of a creator's feed)
rendered a big empty 'No images attached to this post' placeholder taking half
the card. Render the media column only when the post HAS images; image-less posts
let the title + body span the full width. Removes the now-dead PostEmptyThumbs.
